Adding lights to dresses and shirts is nothing new. We have already covered plenty of cool wearables with lighting effects. Want to make your own? MikaelaHolmes has posted a guide that shows you how to make your own LED skirt. The skirt lets you put on a better show at night. Of course, you can keep the LEDs off.
The developer used a pre-programmed LED chip that can be controlled by a remote to complete this project. Of course, you could use Arduino to come up with a more sophisticated solution. More information is available here.
